Transcribe the label mass
Enter the complete mass printed on the label and preserve the milligram unit in the worksheet.
Record final volume
Enter the final prepared volume in millilitres. Concentration is calculated from mass divided by that volume.
Enter the protocol-defined mass
Use the mass already specified by the approved research protocol; the unit toggle converts between micrograms and milligrams.
